Definitions

  • the invention refers to an at least partially striking and rotating hand tool such as a combination hammer with a locking switch of the engine switch for the chisel, according to the preamble of claim 1 and as from US2003226673A1 known.
  • the motor switch of the motor control is locked in the on state with a locking switch, but not for the rotating other operating modes.
  • the locking switch for the motor switch is formed as a in (for appropriate handling) lower handle bar of the guide handle multi-piece hinge-mounted locking clip, which is connected to a nadoversetzbaren mode selection switch the percussion unit.
  • a hand tool vibrating along the striking axis has a motor switch in a guide handle, on whose (with appropriate handling) upper handle a locking switch is arranged, which locks the motor switch in the fully on state.
  • the object is to realize a technologically simple control of the locking switch for the motor switch in a vibration-decoupled guide handle.
  • a hand tool machine which at least partially hammers and rotates along a striking axis has a guide handle with a motor control motor switch, which is assigned a locking switch which can be displaced in a switching range, and an operating mode selector switch is arranged in the striking mechanism assembly. which displaces a shift linkage, wherein the shift linkage has a stop which projects into the shaft region in a rotating operating mode.
  • the lock By controlling the locking function on a loose, not connected to the locking switch stop, the lock is fatigue-free and technologically easy even with a vibration-decoupled to the striking mechanism assembly guide handle.
  • the locking switch elastically deforms a flexible leaf spring which is fixed at one end and forms a hook at the other free end, which engages positively in an associated recess of the engine switch actuated in the on state, whereby a robust and simple technological locking is achieved.
  • the leaf spring (with appropriate handling) arranged in the upper handle, whereby no space in the lower handle is consumed, which thus remains fully available for other assemblies.
  • the locking switch on a manually displaceable in the axial direction slide on, further advantageous on the upper side of the housing upper handle bar, whereby this is ergonomically with the thumb handle operable guide handle included.
  • the leaf spring forms within its axial extent a nose oriented towards the slide, on which the axially offset slide slides at least partially along, whereby the hook is positively pressed into the recess of the motor switch actuated in the on state.
  • FIG. 1 has a along a striking axis A beating and rotating hand tool 1 in the form of a combination hammer with respect to a percussion unit 2 with a rotatable in the rotating and beating rotary drilling mode and the only beating chisel mode Hormodi inchesschalter 3 vibration-locked guide handle 4.
  • a motor switch 5 is arranged for motor control, which is lockable with a arranged at the top of the upper handle bar 6 locking switch 7 in the form of an axially longitudinally displaceable slide in the ON state.
  • Fig. 2 and 3 is connected to the operating mode selector switch 3 connected in Drehbohrmode via an eccentric 8 a shift linkage 9 axially on the handle side, whereby a stop 10 protrudes into the switching range X of the locking switch 7, whereby this is not sufficiently far schlagwerks person displaceable for locking the motor switch 5 to the associated nose 11 to press a flexible leaf spring 12 which extends axially in the upper handle bar 6, at the free end forms a hook 13 and is connected at the other end to the handle assembly 14.
  • the shift linkage 9 is axially offset on the percussion side, whereby the stopper 10 does not protrude into the shift range X of the arresting switch 7.
  • the locking switch 7 is set to the locking side of the engine switch 5, wherein the associated nose 11 of the flexible leaf spring 12 is actuated and deformed elastically. As a result, the hook 13 engages positively in an associated recess 15 of the motor switch 5 operated in the switch-on state.
